Helium-3 is a non-radioactive hydrogen isotope with one neutron and two protons. It is carried through space via the Sun’s solar winds, but burns up as it enters Earth’s atmosphere, making it almost non-existent here on our planet. However, an abundance of helium-3 has built up on the Moon’s surface over the millennia as confirmed in soil samples collected by the Apollo 17 lunar mission, and it is just waiting to be mined.
